I'm new to owning a home. Someone told me that I have to run my oil
forced air furnace once a month in the summer to keep the furnace from
rusting. Is this true? I have a hard time accepting this as I'm trying
to cool the house off..why turn up the heat?
Running it one a month wont help. High basement humidity will rust
everything, you will notice your tools first, running it once a month
only dries it out for a few hours, if your humidity is to high get a
dehumidifier. But will it make it last longer, maybe not.
Never heard of that.
Closest thing to that was running the car AC every 2-4 weeks in winter to
keep the seals lubed so they don't dry out. How true is that? Dunno for a
fact. Maybe another old wives tale.
It might have been true when A/Cs first came out,
but later it didn't make any difference. The
point is moot anymore because most modern vehicles
run the A/C automatically under many heat
settings, most common is the A/C running whenever
the defrost is turned on. My pickup has about 8
settings and it runs the A/C with all but 3 settings.
I own a 1988 Buick in mint condition. The A/C worked fantastic until
this season, when it appears to have lost some R-12 as the clutch is
short cycling the compressor.
The problem is that the R-12 will have to be recovered and then it will
need leak testing with a 700-micron or below vacuum drawn and then
charged with a refrigerant replacement. The refrigerant hoses may need
to be replaced for the new refrigerants. Your opinions... .
What is the score on Autofrost/R-406A replacing R-12?
I need all the information anyone has concerning not having to recover
the R-12 yet!
It could be just a clutch problem, I need to have it checked.

Can't help much, but I can tell you that you can't
trust even major car dealers on A/C repair. I had
a clutch burn up on the A/C of a 1973 Pontiac, oil
got on the pads and swelled them just enough to
burn up the rubber attachments. I told them it
burned up when I didn't have the A/C on. They
told me I need a new compressor even though it was
obvious that the compressor had nothing to do with
the clutch burning up. The jerks fixed the clutch
but didn't fix the idler bearing (which I asked
them to include) and it seized in another 5-10,000
miles. Bought the tool and did it myself with a
completely new bearing and clutch since the
package cost about the same as one of the components.
If you are going to have someone do the work, I
suggest you just buy a new car!
